properties but also to discriminate and map burned areas. As shown by Lentile et al. ( Lentile et al. 2006 ), in most environments and fire regimes and at the spatial resolution of most satellite sensors (>30 m), burned vegetation results in a drastic reduction in NIR surface reflectance; this is typically accompanied by a rise in shortwave-infrared (SWIR) reflectance. Thus, several spectral indices have been created to integrate the NIR and SWIR bands, both of which register the strongest responses, in

geodatabase of fire-affected areas. However, the proposed approach to some extent depends on the parameterization of the fuzzy membership functions, which in this case is done with a partially data-driven approach to cover the wide range of spectral properties of burned areas in the Mediterranean environment of Southern Italy. Clearly, it can be applied automatically where these conditions are met, and further tests should be carried out if the algorithm has to be applied to different biomes. Indeed, this
